To all whom it may concern:

Be it known that I, FRANK B. Riincitizen or the United States, residing at Springfield, in the county of Windsor and State 01 Vermont, have invented certain new and useful Improvements in Vehicle Driving-Gear, of which the following is a full, clear, and exact specification.

This invention relates to motor vehicles, and. more particularly to the driving mechanism.

An object oi. this invention is to provide at rear axle shaft driven vehicle having the motor mounted at the front and driving a shaft including universal joints alined in a. horizontal plane therewith; in addition to said shaft the motor is connected with the live rear axles by clutches and driving and differential gearing, so as to permit a desired gear reduction between the wheels and the motor. In the 'pre'ferred form of my invention the rear gear of the driving shaft is disposed shove the diilerential, snid gear driving the differential through a gear fixed on the exterior of the casing of the differentiel.

Qther objects and features of in invention will he more fully understood from the following description and the occoznpanying drawings. wherein- Figure l is a side elevation of a driving mechanism for a vehicle and embodying my invention; Fig. 2 is a plan view; Fig. 3 is a detail plan of the reducing gearing, and Fig. i is a vertical section through the line l, 4% of 3.

Referring to Figs. 1 and 2. the side frames. 1, l of" the vehiclenre provided with crossbars 2, 3, 4., 5, axles 6, 7, Wheels 8, 8, 9, 9. The steerin' wheel is connected with the Wheels 8 through the post '11; the springs 12, 12, 13,13, are of the usual construction.

The vehicle is provided with a dash and a removable hood 16, the letter inclosing the motor and driving parts. The live axles T. 'l are driven from an electric motor carried low in a curved cradle by a shaft 21 through hovel gears (ll, 52 in the casing 29., and spur gears 66, (37, the latter being on, :1 differential casing 68 containing diilerential gesrs connecting the live axles 7. This applies a double reducing gearing upon the motor shaft and the Wheels. T he universal pints 2'! allow for the springing of the vehicle body. In this construction it will he noted that the gear 61 is disposed above the diii'erential casing 68, tlnis perniitting the shaft 21 and universal. joints .37, 2? ll; he arranged in :1 substantially straight line 111 a horizontal plane, thus avoiding the ob jectionable feature, common in prior devices, of tipping the motor shaft. The rootor 20 is mounted in the front or the vehicle under the hood l6 and drives the shaft 21 through a clute. 533 which is eontrolled by a lever and fork, as will be understood. The current for the motor is supplied lov 0. storage battery so hung from the middle of the vehicle body between the Wheels. The battery is divided longitudinally into two sections between which the driving shaft 1 31 passes. The electric controlling means ere clescrloed more fully in my ogpliozrtion,

Serial Number 379,593, filed June 18, 1 .907,

of which application the present appliestion is e division.

Mounted in front of the motor is s engine 28, of any desired type, with e. flv- Wheel 29, and adapted to drive the motor shaft through a clutch 30. This clutch has a fork 18. operated by a lever 17. The vehicle will carry a. supply of fuel for the engine and suitable connections and accessories will also be provided. Under normal conditions, the storage battery supplies current for the motor, and. the latter drives the shaft 21 and the wheels through clutch 23, which will he closed and held lay the rack. Also, the Wheels can drive the motor as a generator or brake through the clutch 23 as well as the engine. The clutch will be out and the movement of the motor thus does not ali'ect the engine 28, which therefore remains at rest and the fuel cut oil. in case it is desired to drive the motor as a generator by the engine to charge the battery, the clutch 30 Will be thrown in and the clutch 23 out, thus preventing any movement of the vehicle, and the output of the motor can .be governed by means of switching apparain I ' in 1:...zctice cmnbine' ngs 31, 31.
